Claims
- 1. An ethylene-vinyl acetate copolymer composition comprising a blend or melt kneaded product of
- (A) a saponification product of an ethylene-vinyl acetate copolymer or a grafted product of the saponification product and
- (B) at least one compound selected from the group consisting of pyromellitic anhydride, a diester of trimellitic anhydride with ethylene glycol, a triester of trimellitic anhydride with glycerol, a diester of pyromellitic anhydride with ethylene glycol, a triester of pyromellitic anhydride with glycerol and 3,3',4,4'-benzophenonetetracarboxylic acid anhydride.
- 2. An ethylene-vinyl acetate copolymer composition comprising a blend or melt-kneaded product of (A) a saponification product of an ethylene-vinyl acetate copolymer or a grafted product of the saponification product, and (B') a diester of trimellitic anhydride with ethylene glycol.
- 3. A composition according to claim 1 wherein (B) is present in an amount ranging from 0.001 to 20% by weight of (A).
- 4. A composition according to claim 2, wherein (B') is present in an amount ranging from 0.001 to 20% by weight of (A).
- 5. An ethylene-vinyl acetate copolymer composition comprising a blend or melt kneaded product of (A) a saponification product of an ethylene-vinyl acetate copolymer or a grafted product of the saponification product and (B) at least one compound selected from the group consisting of a diester of trimellitic anhydride with ethylene glycol, a triester of trimellitic anhydride with glycerol, a diester of pyromellitic anhydride with ethylene glycol, a triester of pyromellitic anhydride with glycerol, and 3,3',4,4'-benzophenonetetracarboxylic acid anhydride.
- 6. The ethylene-vinyl acetate copolymer composition according to claim 5 wherein the compound (B) is present in an amount ranging from 0.001 to 20% by weight based on the weight of the saponification product of an ethylene-vinyl acetate copolymer or a grafted product of the saponification product (A).
